Default 2.5" header to 2.25" what to do?

Damn I just dropped $500 on a speedstate exhaust, but its a 2.25" piping, if I get a 2.5" 4-1 header will it cause trouble? and should I get get a 2.5" carsound cat or a 2.25" carsound cat?

thankx guys, my knowledge of exhausts has doubled in the last few days thanks to you guys!

i would go with the same diameter to the cat (2.5) then drop it down to 2.25 for the speedstate cat back. That should be fine.

In other words...get the headers...and a 2.5" cat.
